Final answer:
Buck's environment becomes harsher at the end of Chapter 1, shaping his survival instincts differently.
Step-by-step explanation:
Buck's environment was harsher at the end of Chapter 1, shaping his survival instincts differently.
In the beginning of Chapter 1, Buck lives in a comfortable home in California, where he is pampered and protected.
However, after being kidnapped and sold into the brutal world of dog sledding in the Yukon, Buck's environment becomes much harsher.
He has to endure extreme cold, exhausting work, and physical abuse from the men.
These adverse conditions force Buck to tap into his primal instincts in order to survive.
He becomes more resourceful, resilient, and learns to adapt to the demanding environment of the Klondike.
The changes in Buck's environment greatly impact his development, as he transforms from a domesticated pet to a fierce and independent sled dog.
